What is the major drawback of rutherfords model of the atom?

• Rutherford’s model could not explain why atoms are stable.
• In his model, electrons move around the nucleus like tiny planets.
• Physics says a moving charged particle (like an orbiting electron) should lose energy by giving off electromagnetic radiation.
• If electrons keep losing energy, they would spiral into the nucleus and the atom would collapse.
• But in real life, atoms do not collapse. They are stable. So Rutherford’s model didn’t match reality.

How this was fixed (Bohr’s idea):

• Electrons can sit only in fixed energy levels (orbits).
• While in these allowed orbits, electrons do not radiate energy.
• They jump between levels by absorbing or releasing set amounts of energy.
• This explains atomic stability.
